python - installing wxpython via pip or easy_install


I am running into some problems installing wxpython using pip.


Here is my current output:


[myuserid]% sudo pip install wxpython
Downloading/unpacking wxpython
  Downloading wxPython2.8-win64-devel-2.8.11.0-msvc9x64.tar.bz2 (7.2Mb): 7.2Mb downloaded
  Running setup.py egg_info for package wxpython
    Traceback (most recent call last):
      File "", line 14, in 
    IOError: [Errno 2] No such file or directory: '/Users/myuserid/build/wxpython/setup.py'
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

----------------------------------------
Command python setup.py egg_info failed with error code 1
Storing complete log in /Users/myuserid/.pip/pip.log


  • I have had a look in the pip.log file but it is totally empty.

  • I have tried installing other packages via pip and there are no problems, so I'm concluding that pip itself is working.


I have also tried via easy_install and got the following:


[myuserid]% sudo easy_install wxpython
install_dir /Library/Frameworks/EPD64.framework/Versions/6.2/lib/python2.6/site-packages/
Searching for wxpython
Reading http://pypi.python.org/simple/wxpython/

Reading http://wxPython.org/download.php

Processing wxPython-src-2.8.11.0.tar.bz2
error: Couldn't find a setup script in /tmp/easy_install-faZZOn/wxPython-src-2.8.11.0.tar.bz2


  • Does this mean that there is something going on with the wxpython package as grabbed by pip and easy_install

  • Aside from building from source, are there any other ways to debug or patch this type of response from pip or easy_install?


System Config:



  • OS X 10.6

  • Enthought Python Distribution Python v2.6, 64-bit


If there is any other information needed, please advise and I will post it.

You seem to be new to this... welcome!


The folk at Enthought, who built EPD for you still haven't figured out how to reliably build wxPython for a 64-bit python, see here:


http://www.enthought.com/products/epdfaq.php#mac


So, you are treading into difficult waters. Have you considered going the Qt route? All traitsUI backed apps will easily port over to Qt. Currently, I like the looks of Homebrew for interacting with EPD (e.g. for installing pyQt), but the jury is still out (haven't done it yet). I'd post a link to that too, but I am a 1-point user at present...


Another possiblity would be to also install the 32-bit EPD which already includes wxPython for you. You might then use your 32-bit python for visualization and your 64-bit for serious number crunching.


If you do insist on installing wxPython, note that you won't be able to link the Carbon version (which is stable, but only 32-bit). Instead, you'll want to use wxCocoa (experimental, 64-bit). At least, this is my understanding. The Enthought folk don't make any mention of wxCocoa, and I wouldn't be surprised if there is breakage. TraitsUI is complex and difficult to debug, so be forewarned if you go this route!

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
